The AXKU042 FPGA development board is equipped with four Micron 1GB DDR4
chips, model MT40A512M16LY-062EIT. Four DDR4 SDRAMs form a 64-bit bus width.
Because four DDR4 chips are connected to the FPGA, the DDR4 SDRAM can run at
speeds up to 1200MHz, and four DDR4 memory systems are directly connected to
the BANK44, BANK45, and BANK46 interfaces of the FPGA. The specific
configuration of DDR4 SDRAM is shown in Table 3-1.

Part 2.4: Gigabit Ethernet Interface There is 1 Gigabit Ethernet port on the
AXKU042 FPGA Development board. The GPHY chip uses Micrel’s KSZ9031RNX
Ethernet PHY chip to provide users with network communication services. The
KSZ9031RNX chip supports 10/100/1000 Mbps network transmission rate and
communicates with the MAC layer of the system through the RGMII interface.
KSZ9031RNX supports MDI/MDX adaptation, various speed adaptations,
Master/Slave adaptation, and supports MDIO bus for PHY register management.
When the KSZ9031RNX is powered on, it will detect the level status of some
specific IOs to determine its own operating mode. Table 3-5-1 describes the
default settings after the GPHY chip is powered on.
| Configuration Pin | Description | Configuration value |
|---|---|---|
| PHYAD[2:0] | MDIO/MDC mode PHY Address | PHY Address 为 011 |
| CLK125_EN | Enable 125Mhz clock output selection | Enable |
| LED_MODE | LED light mode configuration | Single LED light mode |
| MODE0~MODE3 | Link adaptation and full duplex |
configuration
| 10/100/1000 adaptive, compatible
with full-duplex, half-duplex
When the network is connected to Gigabit Ethernet, the data transmission of FPGA chip and PHY chip KSZ9031RNX is communicated through the RGMII bus, the transmission clock is 125Mhz, and the data is sampled on the rising edge and falling samples of the clock. When the network is connected to 100M Ethernet, the data transmission of the FPGA chip and PHY chip KSZ9031RNX is communicated through the RMII bus, and the transmission clock is 25Mhz. Data is sampled on the rising edge and falling samples of the clock. Ethernet PHY chip connection diagram as shown in Figure 2-4-1:

Part 2.12: JTAG Interface
The JTAG interface is reserved on the AXKU042 development board for downloading FPGA programs or firmware programs to FLASH. In order to not damage the FPGA chip by plugging and unplugging under power, we added a protection diode to the JTAG signal to ensure that the signal voltage is within the range accepted by the FPGA and avoid damage to the FPGA chip. JTAG schematic diagram is shown in Figure 2-12-1:
Part 2.13: Power Supply
The power input voltage of the AXKU042 development board is DC12V, with an external+12V power supply or power supplied to the board through PCIE. When using an external power supply, please use the power supply provided by the development board, and do not use other specifications of the power supply to avoid damaging the development board. The schematic diagram of the power supply design on the board is shown in Figure 2-13-1
Part 2.14: Fan
Because FPGA generates a lot of heat when it works normally, we add a heat sink and fan to the chip on the board to prevent the chip from overheating. The control of the fan is controlled by the FPGA chip. The control pin is connected to the IO of the BANK48. If the IO level output is high, the MOSFET is turned on and the fan is working. If the IO level output is low, the fan stops. The fan design on the board is shown in Figure 2-14-1.
